a, continuous metal frameouter guide rib 22 in the upper and sideportions of the sash frame for upper sash 24, as shown in Figure 3 ofthe drawing.

The sash frame 29 is also formed at one side edge with an inwardlyprojecting flange 3| which is cemented or otherwise suitably secured ina groove 32 formed in the outer perimeter of a continuous rubber glazingstrip 33 and strip 33 is also formed with an internal groo-ve 34 inwhich the edges of the glass 35 are secured. The edges of flanges 32 andglass 35 overlap to add rigidity to the rubber glazing strip 33.

The side and bottom portions of one of the guide channels 2l or 22 isprovided with a rubber sealing strip 36 which bears against the sides 6and sill 3 and the top of lower sash frame 29 is closed by a rubbersealing strip 3l held in position by the flanges 3l), the sealing strip3l being formed with a lip 3S at its, upper inner edge fitted closelyagainst the rubber glazing strip at the bottom of upper sash 24.

The lower sash 23 is intended to remain stationary while upper sash 24is slidable on the outer guide ribs 22 and the upper sash is held in itsvertically adjusted position by means of pivoted sash locks 39 pivotedon a pin 40 at each upper side edge and on the inside of sash frame 29for upper sash 24, the sash lock being formed with teeth 4I at one endheld in engagement with the sides of sash guide 26 by a wire spring 42coiled about the pivot pin 40 and with one end thereof anchored to thesash lock adjacent its toothed end as indicated at 43 and with the otherend 44 of the spring engaged under a finger gripping ange 45 on a plate46 welded or otherwise suitably secured to the upper corner of sashframe 29.

The other end of sash lock 39 is formed with a forwardly projectingflange 41 opposed to flange 45 and positioned for gripping the flanges45 and 41 with the lingers to swing the toothed end 4l of the sash lockdownwardly into a position for releasing the sash lock for lowering theupper sash 24.

In the operation of the device with the window frame mounted in a bus orother vehicle, the lower portion of sash guide 20 may be forcedoutwardly and released from catch 21 and the sash guide 20 together withthe lower and upper sash 23 and 24 swung outwardly into the positionshown by dotted lines in Figure 3 on hanger 25 at the upper edge of sashguide 20 whereby to provide an emergency exit for persons trapped in thebus.

In view of the foregoing description taken in conjunction with theaccompanying drawings it is believed that a clear understanding of thedevice will be quite apparent to those skilled in this art. A moredetailed description is accordingly deemed unnecessary. f l

It is to be understood, however, that even though there is herein shownand described a preferred embodiment of the invention the same issusceptible to certain changes fully comprehended by the spirit of theinvention as herein described and the scope of the appended claims.

Having described the invention, what is claimed as new is:

1. A window construction comprising a metal frame including a headerhaving an inturned flange, a continuous elongated sash guide framepositioned in the rst named frame, sash mounted in the guide frame, anda hanger strip having a downturned lip engaged'over the flange andvswingably supporting the guide frame at its upper edge in the rst namedframe, said hanger strip and said downturned lip extending throughoutthe length of said guide frame, said strip being rubber to constitute asealing strip as well as a hanger strip.

2. A window construction comprising a metal frame including a headerhaving an inturned flange, a continuous elongated sash guide framepositioned in the rst named frame, sash mounted in the guide frame; arubber hanger strip having a downturned lip engaged over the ange andmeans swingably supporting the guide frame at its upper edge in thefirst named frame, and a catch supported solely by the rst named frameand locking the lower edge of the guide frame, said hanger strip andsaid downturned lip extending throughout the length of said guide frame.A

3. A window 'construction comprising a metal frame, a continuous sashguide frame positioned in the rst named frame, sash mounted in the guideframe, a `rearwardly inclined lip at the upper edge of the rst namedframe` and extending throughout the length of said upper edge, and a'hanger at the upper edge of the guide frame engaged over the lip andsupporting the guide frame for swinging movement, said hanger beingrubber and contacting the lip throughout the length of the lip to form asealing means as well as a hanger.

4. A window construction comprising a metal frame, a continuous metalguide frame positioned in the `first named frame and having inwardlyprojecting hollow guide ribs, upper and lower sash mounted on the ribs,a rearwardly inclined lip on the upper front edge of the rst namedframe, a hard rubber hanger strip having one edge anchored in andcompletely filling the outer rib at the upper edge of the guide frameand having a downturned lip at its other edge extending throughout thelength of the guide frame engaged with the first named lip to swingablysupport the guide frame, and a catch locking the lower edge of the guideframe and underlying the guide frame when the latter is in its closedposition.

5. A window construction comprising a metal frame, a continuous metalguide frame positioned in the first named frame and having inwardlyprojecting hollow guide ribs, upper and lower sash mounted on the ribs,a rearwardly inclined lip on the upper front edge of the rst namedframe, a hard rubber hanger strip having one edge anchored in and llingthe outer rib at the upper edge of the guide frame and having adownturned lip at its other edge engaged with the rst named lip toswngably support the guide frame, and a screw catch threaded inthebottom of the first named frame and having a rounded head engaged in oneof the guide ribs at the bottom of the guide frame to lock the latter.

6. A window structure comprising an open, substantially rectangularmetal frame including an upper downwardly facing channel shaped endforming a header having an inturned horizontal ilange, a continuousmetal guide frame positioned in the first named frame and includinginwardly projecting hollow vertical ribs and upper and lower horizontalribs, sealing strips having one of their edges secured in the verticalribs and their outer edges resting against the first named frame, a hardrubber sealing strip mounted in the upper horizontal rib and having ahook portion extending throughout the horizontal dimension of the guideframe and engaging over the flange to permit swinging of the guide framerelative to the header, said hook portion being provided with a iiatsurface contacting said ilange, and means carried by the rst named frameengaged in the lower horizontal rib to retain the guide frame againstswinging movement.

7. The combination of claim 6 wherein said last named means includes aheaded screw threaded in the first named frame and having its headextending toward the guide frame to enter the lower hollow rib.

8. A window structure comprising a metal frame including a, channelshaped header and a channel shaped sill, said header including aninturned horizontal flange, a continuous metal guide frame positioned inthe first named frame, said guide frame including an upper inwardlyprojecting hollow guide rib, a lower pair of inwardly projecting hollowhorizontal guide ribs and a pair of vertical guide ribs, verticalsealing strips mounted in and projecting outwardly froml the verticalribs and engaging the rst named frame, a horizontal sealing stripmounted in one of the lower ribs for engaging the sill, an upper rubbersealing and hinge strip mounted in the upper rib and including a portionprojecting from the upper rib and engaged over the flange, and meanscarried by and rising from the sill for engagement in the other lowerrib to retain the guide frame normally positioned in the rst namedframe.
